Human feces and urine can be fermented for a few days.

In traditional agriculture in China, human feces and urine have been used as plant fertilizers for too long. In ancient times, when there was no nitrogen, phosphorus and potassium fertilizers, in order to supplement plant nutrients, human feces and animal feces and urine were collected and applied to plants after treatment. The plant ecology, environmental protection, and the yield is still quite high.

At present, human feces and urine are used as plant fertilizer, which can not be directly used in vegetable cultivation, but can only be used after fermentation treatment. Human excretion carries human bacteria, and the feces of some patients carry too many harmful bacteria. When applied to vegetables without fermentation treatment, vegetables absorb nutrients and attract harmful viruses to the human body at the same time. People are very likely to be infected with diseases after eating these vegetables.

How many days can human feces and urine ferment be used?

According to the local weather temperature to determine the fermentation time, in the summer generally 3Murray 5 days, must be fully mature can be used.

Fermentation method of human feces and urine

The method of flat fermentation of human feces and urine is to dig some field mud on the flat ground to lay the bottom, then spread straw grass, sprinkle plant ash, pile up the dung, pile 10 centimeters thick and sprinkle lime on top, then lay a layer of straw grass, then pile up about 10 centimeters of dung, then sprinkle lime, the pile is 1.5 meters high, the outside of the dung pile is also covered with lime, and then covered with straw grass, and then sealed with field mud. In order to be waterproof, a waterproof film can be added to the outside, so that the stacked human feces and urine can be fully fermented and mature in half a month in summer. Due to the low temperature in winter, the fermentation time will be more than doubled.
